Original application filed December 22, 192i, Serial Ila-524,150, Divided and this application filed May a 9,1922. sr1a1,m.'55s ,55e.

To (ZZZ whom it'mwy concern Be it known, that I, Former A. S'rAIN- BROOK, acitizen of the United btates, and a resident of Boston, in the countyof" Suffolk and State of Massachusetts, 'haveinvent'ed a new and use-fullmp'rovement in Electrical Drink Mixers, of which thejollowingis a specification.

My invention relates to electricalmixers of the alternating-current motor .typ'e"wherein' there is no mechanical connec element of the agi-.

tion between the drivin tater disposed in the liquid receptacle and the outside energizing element.

The object of my invention is to provide an electrical drink mix'erhaving the agitator driving-element mounted for rotation in a removable resilient device arranged to be sprung by the elasticity thereof against' the lnner sides of the liquid receptacle whereby the agitator and V readily be removed for cleansing from said fully appear from the following detailed description taken in connection with the accompanying drawings. v

With the foregoing-objects in yiewmy i'nvention comprise's a liquid container which may be of glass 'orother dielectric material and a tripod or the like of spring material having its feet sprung by the elasticity thereof against the inner sides of saidreceptacle, said tripod carrying a bearing for the rotor, a rotor journalled in said bearing and a stator in co-operative' relation with said rotor, said stator preferably being located in a casing having a depression for receiving said container so that when the latter, is placed in. said depression, 1 the stator and rotor will be arranged in the same plane.

This application is a division of my application' Ser, No. 524,150, filed December 22, 1921.

In the drawings which accompany and form a part-of thisspecification -r Figure 1 is'a vertical section of an electri cal drink mixer embodying-my invention';

Fig. 2 is a plan view of a modification in which the rotor is so constructed as to'perform the function of an agitator;

as soon as the receptacle is removed from said depression, the spring 24 arranged between the boss 25 and the collar 26 fixed to the stem will move the latter upwardly,

' thereby compressing the spring 27 arranged between said collar 26 and the circuit closer. As soon as the compression of the spring 27 is sufiicient to overcome the grip of the clips 17 on the circuit closer, the latter is'shot 'Ser. No.-559, 554, filed simultaneously here- .with.

depression 11 of the casing, the stem 19 will Arranged within the mixing vessel and resting on the bottom thereof is a tripod'of spring material having its feet 28 sprung by the elasticity thereof against the inner upwardly as well as downwardly from the radial arms 29 thereof, and the lower end of the shaft 31 is provided with a point 341 which rests on the bottom of the. vessel, al v though it will be obvious that other arrangements may be em loyed for positioning the rotor in the vessei and for affording a suit able bearing for the same on the bottom thereof.

As shownin Fig. 1 the rotor consists of a solid ring connected by the spokes 35 to the central hub rigidly attached to the shaft 31,

although, as will be apparent, said rotor maIy be a solid metal disc. a

11 Figs. 2, 3, and 4, I show a modification wherein the rotor 15 consists of a ring connected to the central hub' 36 by the arms 37 which, as indicated in Fig. 4, are inclined to the horizontal and therefore perform the In this case the function of an agitator. shaft 31' will preferably terminate at the up r end of the bearing 30.

bodiments of my invention without however I limiting the same thereto, what I claim and desire to secure by Letters Patent is 1. An electrical drink mixer comprising in combination a liquid container, a rotor, a removable resilient means in the bottom of said container'for rotatably mounting said rotor therein, and a stator in co-operatlve relation with said rotor.

2'. An electrical drink mixer comprising in combination a liquid container, a tripod of spring materialhaving its feet sprung by the elasticity thereof against the inner sides of said receptacle, a rotor, a bearing for said rotor carried by said tripod, and a stator in coroperative relation with said rotor".

Anielectrical drink mixer comprising" i in combination a 'liquid' container a rotor, a bearing for said rotor, radlal arms carrymg said bearing, reslllent members secured to said arms respectively, andarranged to be I sprung bvtheir elasticity a ainst the inner sides of'said receptacle, an astator in cooperative positionw-ith said rotor.

4. An electrical 'drink mixer comprising in combination a liquidcontainer, a rotor :rotata'bly -mounted therein, said rotor consisting of a ring of magnetic material, a hub,

and arms connecting said hub and ring, said arms being inclined to the axis of said ring,

and a stator in co-operative relation with sa d rotor. l
